Hart .257 barrel

I've got a Hart, 26" fluted, #10 twist, #4 contour, chambered by Dan Dowling with a short throat 257 Weatherby reamer. It is coated in birdsong black t and had around 300 rounds thru it. It has enough shank that it should be able to be setback if you want. At present it shoots 80 ttsx at 3800 fps into tiny little groups and 110 accubonds over 3400 fps into sub .5 moa groups with a clean bore. Threaded and on a long action Rem 700 now. $260 shipped.

I want to swap out to a Rock 9 twist in 7mm so thought I would see if anyone was interested in this barrel. Shoot me a pm and we can discuss. Thank you
